3. Test design
According to the medication schemes of tables 1-4, 4 times of spraying and 1 time of pouring are carried out on 2 types of waxberry trees in different periods, wherein the spraying time is respectively 2023, 3, 13, 7, 25 and 9 months, 13. Blank control was set at the same time: spraying the same amount of clean water. Dividing the waxberry wilting disease into I, II, III, IV, V grades according to different degrees of the waxberry, wherein plants with few branches affected by the disease and fallen leaves and unaffected growth are classified as grade I; plants can continue to grow and less than 30% of fallen leaves are divided into II grades; a small part of the branches are dried and 30% -60% of fallen leaves are divided into III grades; part of branches die and more than 60% of fallen leaves of the whole plant are divided into IV grades; the root system and the trunk of the tree body survive, and all fallen leaves and branches on the overground part are dead and divided into V-level.
The application adopts the modes of spraying and pouring, and the statistics of the waxberry wilting disease grades is carried out before each spraying and after the whole-course application. Before the medicine, 8 trees are selected and marked according to the disease condition of the waxberry tree in the test place, and 40 trees are selected and marked for test tracking examination in the healthy adult tree.

4. Test results
As can be seen from tables 5 and 6, the 4 dosage regimens of foodtree, foodtree + Wo Gufu, xunda and Zhengzhenghai sea island element all have the prevention and treatment effects on the infected adult tree wilting, and have the better prevention effect on the healthy adult tree. The control effects are fosamite + Wo Gufu, fosamite +voilet +islands in the industry and fosamite in turn, wherein the best control effect is fosamite +vojiafu.
After the foodware + Wo Gufu is adopted to spray and pour the infected adult myrica rubra for 1 time for 4 times, the diseases are effectively controlled, and 72.5 percent of plants are all of a lighter I, II grade; the application of fosamite + Wo Gufu has obvious prevention effect on healthy adult trees, and only 1 healthy adult tree has slight infection, and no death plant exists. Therefore, fushuai + Wo Gufu is the best for preventing and controlling healthy adult trees and infected adult trees. After the fosamite is used singly, the I, II level of the plant with lighter disease accounts for 67.5 percent; the I, II grade of plants with lighter incidence of the applied Xueze plus the forward sea island element accounts for 65 percent; the I, II level of the single-use plants with lighter disease is 52.5 percent; the I, II scale of the control less ill plants was 20%.
The prevention effect of the Fushuai to the waxberry wilting by using Fushuai plus Wajiafu treatment is 92.3 percent, the prevention effect of the Fushuai to the waxberry wilting is 84.6 percent, the prevention effect of the Fushuai plus the Zhengzheisu to the waxberry wilting is 69.2 percent, and the prevention effect of the Fushuai to the waxberry wilting is 46.2 percent. Fushuai obtain + Wo Gufu has the best effect of preventing and controlling the waxberry wilting.
